Application filed July 11, 1917. Serial No. 179,941.

1 '0 all 10 7mm it may concern Be it known that I, Emma L. PowL, a citizen of the United States, residing at ll. I). #1, Lancaster, in the county of Lancaster and Stateof Pennsylvania, have invented a new and useful Receptacle-Filling Machine, of which the following is a specification.

The subject of this invention is a receptacle filling machine intended primarily for filling receptacles with liquid, and wherein vertically reciprocating valves for controlling the supply of liquid are cooperatively associated with horizontally moving can conveyors, and the objects of the invention are, first, to provide a can filling machine which will deliver fixed quantities of liquid to a can, second, to provide adjustable means for regulating the quantity of liquid to be delivered to each can, third, to provide an intermittent motion for delivering and removing the receptacles, fourth, to provide amachine which may be easily disassembled and cleaned, fifth, to provide a simple and efficient can filling machine.

With the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of my invention herein disclosed can be made within the scope of what is claimed, without de arting from the spirit of the invention.

ne practical embodiment of the invention is shown in the accompanying draw ings, wherein Figure 1 is a front elevation of the machine showing the front door open and the tank sectioned on the line 1-1 of Fig. 3, and the conveyer removed.

Fig. 2 is a. side elevation of the machine; a part of the conveyer broken away.

Fig. 3 is a top plan view wlth a part of the conveyer broken away.

Fig. 1 is a detail cross section on the line 44 of Fig. l.

Referring to the drawings by numerals of reference The machine proper is supported in a suitable framework and casing indicated generally at 1 which may be cast in one piece and mounted on rollers 2. The open front of the casing is closed by a door 3 which swings on hinges 1 while the frame work at the front is joined by the transverse t1e pieces 5. A hanger 6 depends from the cross piece and alines with a similar hanger, not shown, which depends from a transverse tie piece formed integral with the rear frame work. A horizontally disposed shaft 7 is journaled in these hangers and on this shaft is mounted a worm wheel 8 and a worm 9. The worm wheel 8 is driven by a worm 10 formed on the horizontally disposed shaft 11 of a motor 12. The motor 12 is suitably supported in the frame work 1 and the end of its shaft 11 is ournaled in a standard 13 which is secured within the frame work 1.

A horizontally disposed shaft 1 1 extends transversely of the machine and is j ournaled in the side frame work, and on this shaft is loosely mounted a worm wheel 15. Vorm wheel 15 is formed with one member of a clutch the other member 16 of which is feathered on the shaft and is thrown by a lever 17 to put the mechanism in and out of gear. A mutilated spur gear 18, adapted to mesh with a. pinion 18, is mounted substantially at the center of the shaft 14, and on each end of the shaft 14 is secured a wrist plate 19. An adjustable wrist pin, formed with a hand grip end 20, is mounted on each wrist plate and slides thereon in a guideway 21 and is clamped in place when adjusted by a clamping nut operated through the hand lever 22. A. scale 23 may be provided along the guideway, and a pointer 24:, movable with the wrist pin will indicate the amount of liquid which the machine is set to deliver. A pitman 25 is pivotally secured to each wrist pin from which it rises, and the pitman is formed with an attenuated upper end 26 which passes through the bore formed in a block 27. The block 27 rocks on its trunnions 28 which are journaled in a retaining yoke and a sliding block 30 to which the retaining yoke is secured by tap screws or otherwise.

A. coiled spring 25 surrounds the attenuated end 26 and is confined between a knob 26, secured to the free end of the pitman, and the retaining yoke 29.

. Each sliding block 30 is formed with beveled longitudinal edges which slide in grooves formed in the arms of a U-shaped guide plate 31. The guide plates 31 are bolted or otherwise secured at each side of the casing 1. Each sliding block is formed with an inwardly and upwardly extending arm 32, the horizontally disposed upper end v of which is secured by bolts 33 or otherwise, to a horizontally disposed plate 34. Valves 35, each provided. with a stem 36, depend from the plate 34 to which the upper end of each stem is secured by nuts 37 which are threaded on the stem below and above the with depending edges 42, is supported within the casing 1, by brackets 43, which are secured to the casing 1. The plate all is provided with a series of openings 44. The tank 39 is seated on the plate 41, and the bottom of the tank is formed with a series of downwardly projecting circular bosses 45, each provided with a central circular aperture. The walls of the apertures are stepped is seated a ring 46 which is centrally apertured to form a seat for the valve 35. A liquid supply pipe 4:? and an air supply pipe 48 rise from suitable points on the cover of the tank 39. y

Extending longitudinally of the casing l, and below the plate ll is a track formed of longitudinally disposed rails4c9, which are secured to and supported onthe frame work 1. A platform truck 50, mounted on flanged wheels 51 is adapted to the track and each truck has a rack 52 secured to its under surface and extending longitudinally thereof. The. rack 52 is positioned to be engaged by the teethof the pinion18'. A

' series of cans 53 are placed on the truck in position to be drawnbeneath the ports of the tank 39 and receive liquid therefrom. Bracket arms 54: may be secured to the :framework 1 at the front and rear of the 'machine, to support the outwardly project ingend of the track. I

A. transfer system may be provided for consisting of a supporting frame 55 upon a which the rails 56 are secured. A truck 57.

formed with rails 58'which aline with the rails 49 is mounted on flanged wheels 59 which are adapted to engage the rails 56.

This truck receives the truck from the machine, loaded with filled cans, and maythen be propelled along the rails 56 to one side of the machine. At the end of'the rails 56and their supporting frame 55', and extending at right angles thereto, is another supporting frame 60 upon which rails, adapted to aline with the rails 58 on truck 57 are secured. andthese rails are preferably positioned "parallel to the rails 49. Another supporting frame filfextends from the rear of the machine to the frame 60 and parallel to the v frame 55. This frame has rails 62 secured 65' thereon and is provided with a truck in all as shown and within each opening respects similar to the truck 57 just described.

In practice the device operates as follows':Paint or other liquid is caused to flow into the tank 39 through the supply pipe 47, air at the same time being expelled from the tank through the pipe 48. Trucks are loaded with receptacles and brought into position, as indicated in Fig. 2, and coupled together. The wrist pin is set with the pointer 24 at the point on the scale corresponding to the capacity of the receptacle. The motor 12 is started and the clutch thrown in. As viewed in Fig. 2, the mutilated gear 18 will turn contra clockwise while the pinion 18 will turn clockwise. This will draw a truck with its receptacles into position to be filled. While the mutilated gear is in mesh with the pinion and drawinga truck into position, the spring 25 is being compressed and the valves 35 will be held upon their seats. When the gears 18 and 18 are disengaged the pitman has started to rise and its enlarged portion contacts the block 27 and yoke 29 and raises the sliding block. This causes the plate 34 tobe carried upward, and draws the valves and runonto the truck 57. The truck 57 is then propelled along the rails 56 to their end, where the loaded truckmay be run off the truck 57 onto the rails on frame 60 and the truck 57 returned to its starting point. The loaded truck is now emptied of its full receptacles and propelled to the end of supporting frame 60 where it will run on the truck on rails 62. Here empty receptacles can be loaded on the truck and brought to position to enter the machine.

As will be readily apparent the valves and their seats can be easily removed for cleaning whenever it becomes necessary.

Having described my 7 invention, what I claim as new and desire Patent, is V '1, A receptacle filling machine,-including in the'frame and provided with discharge ports, receptacle supports. means for mov-v ing the supports through the frame to bring to secure by Lettersa frame, a liquid containing tank supported 7 to the receptacle upon the support, said.
